Ukuqeda kuyisinyathelo sokugcina ekusetshenzisweni kwe-CNC futhi kungasetshenziswa ukuthuthukisa ikhwalithi yomkhiqizo. Ukuqeda kungasusa amaphutha okubukeka, kuthuthukise imiphumela yokubuka yomkhiqizo, futhi kuthuthukise amandla okusebenza noma ukusebenza kukagesi.
Njengoba ubhekene nezindlela ezahlukene zokwelapha ubuso, abaphathi bemikhiqizo nabaklami bakhetha kanjani ikhambi elifanele? Ungakhathazeki, ukwelashwa okulandelayo okuvamile kunezinzuzo zako. Uma nje uqonda izici zendlela ngayinye, ungangeza amaphuzu kumkhiqizo.
Okuvamileukwelashwa kobusoizingxenye ze-CNC ezenziwe ngomshini
Isimo sokucubungula
Ubuso bezingxenye ezikhiqizwa yi-CNC machining bubizwa ngokuthi “ubuso obucushiwe”. Ubuso buqinile kodwa bunobukhulu obuqinile bokubekezelelana, okwanele kwezinye izinhlelo zokusebenza zobunjiniyela. Ubulukhuni obujwayelekile bungaba ngu-3.2μm, futhi akukho ukucubungula okulandelayo okudingekayo, ngakho-ke ukusebenza kahle kokukhiqiza kuphezulu.
Ezinhlelweni zokusebenza lapho ukunemba kobukhulu kubaluleke kakhulu kunokubukeka, lo mphezulu womshini wanele. Kodwa-ke, ngenxa yobulukhuni bawo kanye nokuntuleka kokugqoka okuvikelayo, umphezulu unamandla okuvikela aphansi futhi uthambekele ekuklwebhekeni nasekugugeni. Sekukonke, isilinganiso sentengo/sokusebenza sanele kwezinye izimo, kuyilapho ukwelashwa okwengeziwe komphezulu kungadingeka lapho ukuvikelwa kuphezulu.
I-Anodizing inqubo ye-electrochemical engakhiqiza ifilimu ye-oxide ejiyile futhi ebanzi ebusweni bezingxenye ezenziwe ngomshini we-CNC, ngaleyo ndlela ithuthukise ukusebenza kokuvikela.
Le nqubo ingasetshenziswa kuphela kuma-alloy e-aluminium noma e-titanium ngoba anamandla okuqhuba kakhulu. Phakathi nenqubo, i-alloy ifakwa ethangini le-electrolyte eliqukethe i-asidi ukuze lisebenze njenge-anode, futhi ugesi usetshenziselwa ukuhlanganisa ama-ion e-oxygen ku-asidi nama-athomu e-alloy ebusweni ukuze kwakheke ifilimu ye-oxide.
Kunezinhlobo ezimbili eziyinhloko ze-anodization. Ziyinqubo efanayo iyonke, kodwa zidinga ukuthi izingxenye zicwiliswe ezixazululweni ze-sulfuric acid ezinamazinga ahlukene. Uhlobo II lubizwa ngokuthi “i-anodization yokuhlobisa”, ekhiqiza ungqimba olubonakalayo noma olunombala olunobukhulu obungu-4-25 μm; uhlobo III lubizwa ngokuthi “i-anodization ye-hard coat”, olunobukhulu be-coating obungu-125 μm futhi olumelana nokuguguleka.
Sekukonke, ukuqeda okune-anodized kuqinile futhi kuzinzile ngokwezinga, okwenza kube kuhle kakhulu ezimbotsheni zangaphakathi kanye nezingxenye ezincane ezidinga ukusebenza okuphezulu. Kungenye yezinketho ezibukeka kahle kakhulu phakathi kokuqeda okwenziwe ngomshini we-CNC, kodwa izindleko ziphakeme kakhulu.
Ukugqoka ngempuphu
Ukufakwa kwempuphu kufana nopende wokufutha. Okokuqala, ukwelashwa nge-phosphating noma i-chromate anti-corrosion kufakwa ebusweni bengxenye, bese izingxenye zifuthwa ngempuphu eyomile ngesibhamu se-electrostatic bese zifakwa kuhhavini ongaphezu kuka-200°C. Ukufakwa kwe-multi-layer stacking kungafinyelela ukujiya okungu-72μm.
Lokhu kwelashwa ngokwako kungakha ifilimu evikela izingxenye ze-CNC, eqinile, engagugi futhi enhle. Ingahlanganiswa ne-sandblasting ukuthuthukisa ukusebenza kokulwa nokugqwala kanye nokufana kwendawo yezingxenye.
Ngokungafani ne-anodizing, i-powder coating iyahambisana nazo zonke izinsimbi, inokuqina okuqinile, kanye nokumelana okukhulu komthelela, okwenza ifaneleke ezinhlotsheni ezahlukahlukene zokusebenza, ikakhulukazi ukusetshenziswa kwezempi.
Kodwa ukugqoka ngempuphu akunawo amandla okulawula ubukhulu futhi akufaneleki ezingxenyeni ezincane noma ezindaweni zangaphakathi. Ngaphezu kwalokho, izindleko eziphakeme zinganciphisa ukusetshenziswa kwayo ekukhiqizweni okukhulu.
Ukuqhumisa ubuhlalu kusetshenziselwa ukwengeza ukuphela kobuso obungacwebezeli noma obucwebezelayo engxenyeni eyenziwe ngomshini we-CNC. Phakathi nale nqubo, umoya ocindezelwe uhambisa izigidi zama-glass beads engxenyeni, ususa ngempumelelo amamaki amathuluzi kanye nokungapheleli ukuze kudalwe ukuthungwa okufana nohlamvu. Ngokungafani nezinye iziphetho ezifana nokugcotshwa kwe-anodizing kanye nokugqokisa i-powder, ukuqhumisa ubuhlalu akushintshi ingxenye ngamakhemikhali noma ngomshini - kushintsha ukubukeka ngokubonakalayo. Ngokungafani nokugqokisa i-powder okwengeza izinto, ukugqokisa ubuhlalu kuyanciphisa njengoba kususa inani elincane lezinto. Lokhu kuyinto ebalulekile okufanele uyicabangele uma ingxenye yakho inokubekezelelana okuqinile.
Ukuqhumisa ubuhlalu kungenye yezinto ezingabizi kakhulu zokuqedela ubuso, kodwa kudinga ukusebenza ngesandla. Labo abacabanga ukuthi kufanele bahlelele umqhubi oqeqeshwe ngokusemthethweni ngoba ikhwalithi yokuqedela incike kakhulu ekhonweni. Uhlobo lobuhlalu nosayizi osetshenziswayo nakho kuthinta imiphumela. Nakuba kuyinqubo yesandla, ukuqhumisa ubuhlalu kuhlala kuyindlela eguquguqukayo futhi engabizi kakhulu yokuqeda izingxenye ze-CNC ngaphakathi kokubekezelelana.
Iseluleko sokuqeda izingxenye ze-CNC ezenziwe ngomshini
Ngamafuphi, ezingxenyeni ezingadingi isithombe esiphelele kodwa okumele zigcine ubukhulu bazo bokuqala, ukwelashwa kwendawo ngemuva kwenqubo njengokugcotshwa kwe-aloidi noma ukugqokwa kwempuphu kungaba yindlela ephumelelayo. Ukugcotshwa kwe-aloidi kuthuthukisa amakhono okuvikela ezingxenye ze-aluminium noma ze-titanium. Uma ingxenye ingenakugcotshwa kodwa idinga amandla nokumelana nokushayisana, ukugqokwa kwempuphu kunikeza okunye. Ekugcineni, uma ukusebenza kahle kwezindleko kubaluleke kakhulu kunokubekezelelana—futhi ingxenye ingadingi indawo ebushelelezi—ukuqhumisa isihlabathi kungaba yindlela engcono.
Onjiniyela, abaklami, kanye nabaphathi bemikhiqizo balulekwa kangcono ukuthi babonisane nochwepheshe bokukhiqiza ukuqinisekisa ukuthi benza ukukhetha okufanele kwephrojekthi yabo elandelayo. Ochwepheshe bakaKachi banolwazi kuzo zonke izici zenqubo yokukhiqiza, kusukela ekwakhiweni komkhiqizo kanye ne-prototyping kuya ekukhiqizweni ngobuningi. Ithimba lethu lingakusiza ukhethe ukwelashwa okuphezulu kakhulu kwendawo yezingxenye zakho ze-CNC futhi liqinisekise ukuthi uya emakethe ngomkhiqizo oqediwe oqinile, osezingeni eliphezulu. Uma kudingeka, sicela usithinte.
